Abstract: A method is disclosed for the preparation of an antimicrobial botanical active from a natural plant.

Abstract: Botanically derived anti-irritants for prophylactic and therapeutic treatment of adverse skin reactions from application of transdermal or topical drug delivery system, permits the effective administration of a drug from a delivery system in which the drug, of a component of the delivery system comprises a skin irritant; and the delivery systems formed thereby.

Abstract: Methods and compositions for suppression hydrocarbon fumes, and cooking oil fumes, by applying a non-volatile organic compounds having a vapor pressure temperature greater than the vapor pressure temperature of the hydrocarbon fume constituents, or cooking oil fume constituents; said compositions may include delivery vehicles such as 70% ethanol, or thixotropic lotions, to produce remediation formulations that may be sprayed or spread onto the surfaces from which the fumes are emanating; also included is an insect repellant, comprising non-volatile organic compounds having a vapor pressure temperature greater than the vapor pressure temperature of the human pheromones and body odors with attract biting insects.

Abstract: A method of sequestering volatile fragrances by encapsulating them in the oil phase of a thixotropic microemulsion, and drying to a thin film, and subsequently releasing the volatile oils upon rehydration of the dried film; compositions comprising the volatile fragrances encapsulated in the oil phase of a thixotropic microemulsion, which compositions may also contain temperature sensitive ingredients; and a wound dressing comprising a dried film formed from a thixotropic microemulsion.

Abstract: Anti-irritant botanical extracts, and a method for screening, and then preparing, anti-irritant botanical extracts for use in topical formulations, providing a natural ingredient capable of preventing skin irritation when in combination with other active and inactive ingredients that have the potential to irritant skin

Abstract: A thixotropic microemulsion for the treatment of mammalian skin; and methods for the preparation thereof; and skin treatment formulations formed therefrom. The delivery system is an oil-in-water type emulsion that is especially useful as a vehicle for the delivery of hydrophobic and hydroalcoholic plant extracts having anti-irritant and/or anti-oxidant properties. The delivery system is comprised of natural, hydrophobic, chemically-modified type starches and polysaccharaides. Among the oils preferred in this embodiment are: mineral oil, petrolatum jelly and silicone oils, either added singly or in various combinations. Among surfactants employed as emulsifiers are: either a cationic detergent, e.g., benzalkonium chloride, an anionic, e.g., sodium lauryl sulfate, and a non-ionic detergent, e.g., Triton X-100 or combinations of oils and surfactants. The resulting emulsion is a semi-viscous and thixotropic gel, which is stable upon prolonged standing at ambient storage temperature.
